I have gotten quite a few people asking me why I am able to fix the MSD SD-1 and MSD SD-2 cap rot boards even after they have spent big money with other people replacing the caps
the answer is simple, I do way more than blindly replace the caps and pretend that will fix it

this is in no way to be considered a guide or how-to or step by step
its just me sharing a little bit of how I work on them and a few picks to hopefully help others fix their own drives

I do LOTS of cleaning and scraping , adding flux and solder, removing flux and solder until it looks clean and all the barrels are cleaned out
then ohm the traces to find any non obvious cracks in the traces, then start repairing the bad traces or vias or barrels
then reassemble and test, if it passes I coat all the repair work so it will not oxidize

I figured I would share picks of some of the fun, you may need to zoom in to see some of the trace repairs
I just got done with my 2nd board this week and only have a backlog of 5 more to fix

Ray Carlsen does the same thing with all the MSD's he handles. FWIW, all the MSD's raffled off at CommVEx have been rebuilt by Ray.

I see that I have been bringing Ray MSD drives since at least 2011 and 2012. See

lol I knew you would flap your lips about that .....seeing you don't really DO anything but talk
I 100% agree RAY is the man he IS the go to person
I talk to RAY myself....I even sell him the switchless jiffydos boards he installs for people
but to burst your bubble I am sorry to inform you ....... RAY has told a few people he does NOT want to fix the boards .....
and the boards where sent to me .......
oh yes and I will be supporting CRX Commodore Retro eXpo again
and as I said ....the picks are to HELP people wanting to fix the boards on their own , you know actually fix it themselves , you should try it once

be sure to ask him who builds the switchless jiffydos boards for him

and tell him I said hello
maybe he will show you the sx64 jiffydos board with built in dual reset , even tho is is the old model and I have a newer version of it
and to be clear .....when people ask me to fix the MSD or ANY CMD device , I send them to RAY first as I think is is great

I'd rather promote others than myself, i.e, Ray Carlsen should get the credit. More to tell Ray tomorrow, Robert Bernardo Fresno Commodore User Group www.dickestel.com/fcug.htm

please do tell RAY and make sure you come back and tell everyone what was said!!!!
he has my email so have him email me ...I dare you to !

I have ALL the emails to backup what I said!

I'd rather promote others than myself,...pure BS ....very first thing from you was promoting CommVEx .........

I on the other hand was posting pictures of damaged boards for others who CAN SOLDER, unlike you who needs someone to fix stuff because you CANT!!!!
